http://thehellfire.net - Hellfire Club is a high end raid guild on CT, raiding 4 days a week:
Wednesday and Friday, 8pm - 11pm EST
Saturday and Sunday, 1pm - 5pm EST

Progression:
we're not a bleeding edge guild in competition for cross-server firsts, but we are in the top 15 of progression guilds in EQ currently, and have been first in progression on the CT server for many years.

Requirements:
we're not terribly rigid about this, but as we are doing higher end content we necessarily need people 'physically' capable of handling the content we're on.
as such, we expect at least 3.5k AAs and a full set (or equivalent) of the current expansion's top tier group armor and augs.

We are currently looking to pick up 2 or maybe 3 more druids.

We have an extremely relaxed attendance requirements for a guild at our tier (far as i've seen of other guilds, anyways) - we are one of the top 15 guilds for progression across all servers, but with a 4 day a week raid schedule.
If you're interested in high end raiding in a relaxed and adult environment, HFC is a good place to look.
